Description

  The present invention relates to a sewage malodor prevention device for preventing malodor caused by backflow through a household sewer or road manhole sewer. Provided is a sewer odor control device capable of improving the amount of water flow by reducing the degree of water, ensuring a long life, and increasing the drainage speed of sewage.

  As is well known, sewers are used to discharge rainwater and sewage that is thrown away at homes, factories, hospitals, etc., and such sewers are sewer pipes buried underground and discharge passages above the sewer pipes. However, an installation port is provided on the ground side of the discharge passage, and a sewer lid having a grating structure or a plurality of through holes is installed in the installation port. Thereby, after various sewage flows into the sewer pipe through the sewer cover, the sewage passing through the sewer pipe is discharged to the sewage treatment plant.

  On the other hand, a malodor that reversely flows in the sewer pipe can be prevented by providing a malodor prevention means having a predetermined discharge passage on the sewer installation port side.

  However, the conventional bad odor prevention means has a disadvantage that foreign matter contained in the sewage or various precipitates enter the discharge passage side and the sewage discharge is not smooth. was there. As a result, Japanese Patent No. 10-068937 (name: sewer foul odor prevention means, hereinafter referred to as the "prior registration patent") has been disclosed which facilitates drainage of sewage and improves odor prevention efficiency.

  The pre-registered patent includes a sewer mounting part and a main body made of a synthetic resin material extended to the sewer mounting part, and the main body part is opened when sewage is discharged, and is closed when sewage is not discharged. It is characterized by preventing the bad smell of the sewer from flowing backward.

  However, the previously registered patent has a disadvantage in that the body portion made of a synthetic resin material is easily damaged when a pedestrian throws out a cigarette fire through a sewer cover or discharges hot water. In order to solve this problem, the present applicant has filed an improved apparatus for preventing sewage malodor through Korean Patent Application No. 10-2007-0106332.

  The sewer foul odor prevention device previously filed by the applicant of the present application is a mounting part attached to the sewer side, a communication part connected to the mounting part, and extended to a lower part of the communication part so that each inner surface is in close contact with each other. A first side wall part and a second side wall part that can be spread, and a main body part having a first corner part and a second corner part that connect both ends of the first side wall part and the second side wall part, The main body is composed of a synthetic resin base material and a heat resistant coating layer coated on the inner and outer surfaces of the base material.

  However, the sewer odor control device previously filed by the present applicant has a structure in which the elastic band is horizontally arranged in a direction orthogonal to the water passage of the communication part, and therefore, when opened, the entire elastic band is opened. Since the uniform drainage pressure must act, there are the disadvantages that the opening / closing operation is not smooth, and there is a problem that the life of the elastic band is short due to the high degree of fatigue.

  The present invention has been created in order to solve the above-described problems of the prior art. The object of the present invention is to provide an elastic band provided in the main body portion that is obliquely arranged at a predetermined angle, and an inlet of the mounting portion is provided.

  As a preferred feature of the present invention, the mounting member is configured such that the lower surface is elastically deformed when being in contact with the ground while maintaining watertightness, and a soft sealing flange projects to form the support member. The plate portion and the neck portion are circular or quadrangular.

  As another preferred feature of the present invention, the fastening element is an upper surface of a flange portion formed by extending a fastening band or an end portion of the mounting portion that surrounds and tightens the outer surface of the mounting portion fitted to the outer surface of the neck portion. And an upper coupler and a lower coupler which are provided in contact with the lower surface and are screw-coupled to the bottom surface of the support plate portion by forming mutually matching screw holes.

  As another preferred feature of the present invention, the discharge unit is provided with two or more inclined elastic bands on both side surfaces with a vertical interval, or provided with an inclined elastic band on one side surface and on the other side surface. Is provided with an elastic plate made of elastic silicone material, urethane material, rubber material, or synthetic resin material.
